Radar: Is it a new technology applicable to water level gauging?

Abstract

The methods of water-level gauging used in some countries (float method with float shaft and station house) require costly investments and need permanent maintenance. Radar-sensor techniques for water-level measurements might be a cost-saving alternative. The paper presents practicability studies of radar sensor applications in water gauging and identifies the limits of applicability. Moreover, first experiences with radar sensors for wave-height analysis are reported.
